A comment from a
Brit chic...
Harriet: still mildly popular in some parts of the UK today.
Rupert: Never met a
Rupert, it's very "upperclass" and I live in a middle class very British Asian sort of area...
Alfie: trendy.
Neville: Not popular at all today, though it may make a comeback, due to popular character
Neville Longbottom (or so I've been told)
Nigel: never met one myself, though I've seen a fair few on TV.
Archibald: to me, this is what someone would think a British person would be called, though in reality they are a
Jack with sisters
Chloe and
Ellie.
Basil: there's a popular kids TV show called
Basil Brush, where
Basil is a puppet fox. I still love the name though, as a GP. I don't think many kids are called
Basil though.
Reginald: Nope.
Reggie I've heard of though.
Beryl: sweet old lady name, I do love it.
Names I personally associate with Britain:
Ellie, as a full name (they are everywhere!)
Freya,
Imogen,
Ruby,
Ava,
Emma (off the top of my head) have been on the rise recently.
Chloe was no 1 for a few years, and is very popular among the sub-culture we know and "love" as chavs (which you can find on wikipedia if you really can be bothered).
Jack has been no 1 for years, so the UK equivalent of
Jacob.
But most names I encounter are Asian or Eastern European, so I'm not a good representative of the whole country.
